I I I Patented Feb. 28, 1950 V CLIP FOR PENS on SIMILAR ARTICLES SamuelKanner, New York, N. Y., assignor to The Gilfred Corp., New York, N. Y.,a corporation of New York Application January 15, 1946, Serial No.641,264

This invention relates to improvements in the construction of retainersor clips for fountain pens and mechanical pencils, and has referenceparticularly to a resilient support for the clip, whereby the latter maybe a rigid member and still perform its proper function of clampingitself to the material of a pocket or other carrying medium. l

The clips ordinarily used in connection with pens and pencils areconstructed of spring steel or other suitable material which allowsitself to be sprung outwardly under pressure to slide over and clampitself to a supporting pocket. After extended use the clip loses itsresiliency at the bending point and breaks.

With this in mind it is the principal object of my invention to providea rigid clip removably mounted in a cap of a fountain pen or directly inthe end of a mechanical pencil, which clip is resiliently urged intoclamping position by means of a separate spring disposed within the capor pencil and adapted to exert its pressure against the clip to hold itin clamping position.

Another object of the present invention is to provide a novel clip ofthe character described which may be readily replaced in case ofbreakage without requiring tools or rivets to make the replacement.

I accomplish the objects of my invention by means of an arrangementhereinafter described, set forth in the appended claims, andillustrativel exemplified in the accompanying drawings, in which:

Figure 1 is a side elevational view of the upper portion of a fountainpen cap or mechanical pencil showing the clip broken away to disclosethe arrangement thereof in the cap.

Figure 2 is a longitudinal, partially sectional view taken on line 2-2of Figure 1;

Figure 3 is a transverse sectional View taken on line 33 of Figure 2.

Referring to the drawings, I denotes the usual fountain pen cap or topportion of a mechanical pencil and comprises a cylindrically shapedhousing having a transverse partition I l disposed in its bore adjacentits outer end, the partition being integral with the housing and havinga longitudinally arranged internally threaded core I2, which isapproximately one half the height of the chamber I3 beyond the partitionII and smaller in its outer diameter than is that of the chamber I3 toprovide an annular space M. The upper or outer peripheral wall of thechamber I3 is provided with an open slot I to accommodate the clip I8.

4 Claims. (01. 24-11) The clip I6 is an inverted L-shaped rigid strip ofmetal or other suitable material, the shorter arm thereof being anannular member I! and the longer arm forming the clip depending alongone side of the cap III. The curved angular section I8 of the clipbegins at the slot I5 and turns outwardly and downwardly as illustratedparticularly in Figures 2 and 3. The clip I 6 is virtually a lever whichpivots on the edge above'the slot I5 and the longer arm of this lever isurged against the exterior of the cap by means of a helical spring I9seated in the annular space I4 of the chamber l3 and adapted to engageunder the shorter annular arm I] of the clip to exert an upward yieldingpressure upon the arm H. The outer diameter of the arm I1 is of theapproximate diameter of the chamber l3 and is held therein and theangular section I8 within the slot I5 by means of a tip 20 which is ofthe diameter of the cap I0 and which is provided with a conical centralopening ZI to receive the conical head 22 of a screw plug 23 projectinginto the chamber l3 and screwing into the threaded bore of the core [2.

To install the present clip I6, the spring I9 is placed in the annularspace I4 and the annular portion I1 is arranged over the spring with thesection I8 projecting through the slot I5. The threaded end of the screwplug 23 is projected through the conical opening 2I and then through theannular portion I1 and into the threaded core I2. As the plug 23 isscrewed down the tip 20 will seat on the end of the cap to close thechamber l3 and the spring will be compressed under the annular portionI! as the conical head 22 seats against the conical wall of the plug. Itwill be seen that operation to open the clip to place it in clampingposition over the pocket will not cause the clip itself to spring at itsangular portion I8, but will simply cause the shorter arm I1 to swinginwardly against the pressure of the spring l9, which will continue toexert its pressure to continue the clamping action.

Having described my invention what I claim and desire to secure byLetters Patent is:

1. A cap construction of the character described, comprising acylindrical shell having an annular chamber, a clip projecting into saidshell over said chamber, a compression spring in said chamber to engagethe clip to cause it to clamp against said shell, and a tip to closeover the shell to hold the clip therein against the pressure of thespring, the said clip being positioned intermediate of said spring andsaid tip in said chamber.

2. A cap construction of the character described comprising acylindrical shell having a transverse partition with an uprightthereaded core, a helical spring embracing the core and projecting abovethe latter, a rigid L-shaped clip having its shorter arm projecting intothe shell Over the core and being engaged by the upper end of thespring, a tip to. close the shell over the shorter arm, and a threadedplug screwed into the core and against the tip to hold the same on theshell.

3. A cap construction, as claimed in claim 2, in which the shorter armof the clip annular in shape to embrace the plug, and the complementaryengaging surfaces of the plug and tip are conical.

4. A cap construction, as claimed in claim 2, in which the upper endwall, or the shell is provided with a slot through which the angularportion of the clip projects to allow the depending longer arm thereofto be yieldably urged against the exterior of the shell by upwardpressure of the spring against the shorter arm of the clip.
